IIPROPATI ZEKHEMICAL

I-Benzene iyilwelo olucacileyo, oluguquguqukayo, olungenambala, olunokutsha kakhulu kunye nephunga elimnandi, elinophawu.Yihydrocarbon enuka kamnandi ebila kwi 80.1 DC.I-Benzene isetyenziselwa i-solvent kwiindawo ezininzi zamashishini, ezifana ne-rubber kunye nokuveliswa kwezicathulo, kunye nokuveliswa kwezinye izinto ezibalulekileyo, ezifana ne-styrene, i-phenol, kunye ne-cyclohexane.Ibalulekile xa kusenziwa izicoci, izibulali-zinambuzane, izinyibilikisi, nezisusi zepeyinti.Ikhona kumafutha afana nepetroli ukuya kwinqanaba le-5%.

Ulwelo lwamanzi olucacileyo, olungenambala ukuya kolutyheli olunevumba elimnandi, eliqhumayo, i-phenolics okanye ivumba elifana nepetroli.Kwi-40 ° C, i-concentration ye-odor threshold ye-190 μg / L emoyeni inqunywe ngu-Young et al.(1996).Umda wevumba we-4.68 ppmv unqunywe nguLeonardo et al.(1969).I-concentration ye-odor yokufumanisa i-108 mg / m3 (34 ppmv) ichazwe nguPunter (1983).I-avareji encinci engabonakaliyo yokuvumba kwe-threshold concentrations emanzini kwi-60 ° C kunye nomoya kwi-40 ° C yayiyi-0.072 kunye ne-0.5 mg / L, ngokulandelanayo.

INDAWO YESICELO

Iinjineli ezimbini / iiNzululwazi / amaGcisa kwiiSuti zeGumbi eliNgqubayo ziSebenzisa iiMicroscopes uLungiso lwecandelo kunye noPhando.Basebenza kumzi-mveliso woMveliso wezixhobo zombane.

Amachiza

Ishishini lamafutha

Umlimi utshiza izityalo eziluhlaza egadini ngemichiza yokutshabalalisa ukhula, izitshabalalisi okanye izitshabalalisi.

Isibulali-zinambuzane

Iigesi ezivuzayo kumbhobho wepetroli okanye wemoto yedizili.

I-diesel Engine Fuel

Gcina umbane ngokuthoba amandla efriji - amandla okupholisa

Isikhenkcisi

I-Aerosol Spray

I-Benzene iphinda iguqulelwe kwi-cyclohexane, esetyenziselwa ukuvelisa i-nylon kunye ne-synthetic fibers.

I-Benzene yenzeka kwimveliso yamalahle kunye netha yelahle kunye nakwimveliso yepetroleum efana nepetroli.Ikwafunyanwa kwiigesi kunye nokuvuza kwenkunkuma kwimizi-mveliso, inkunkuma yokwakha, kunye nenkunkuma yokujonga umhlaba (i-Oak Ridge National Laboratory 1989).Izixa ze-benzene, toluene, xylenes, kunye nezinye izinto eziphilayo eziguquguqukayo zifunyenwe emhlabeni nakumanzi aphantsi komhlaba kufutshane neendawo zokugalela inkunkuma ezininzi (US EPA 1989a,b).UKramer(1989) uvavanye umgangatho we-exposuresto benzene ngexesha lokususwa, ukucocwa, ukumpompa, kunye novavanyo lweetanki zokugcina ipetroli eziphantsi komhlaba.Umndilili wokutyhileka komntu ngu-0.43–3.84 ppm (kwiiyure eziyi-1.5–6) kwaye olona tyhileko luphezulu lwexesha elifutshane (imizuzu eyi-15) lube yi-9.14 ppm.I-Benzene iyenzeka nakwicuba (Hoffmann et al. 1989);ngaloo ndlela umngcipheko wokuba sesichengeni unokunyuka ekusezeleni umsi onjalo.
I-Benzene isetyenziselwa ukunyibilikisa iiwax, iirekeni, kunye neeoli;njengesixhobo sokususa ipeyinti;njenge-diluentfor lacquers;ekwenziweni kwedayi, amayeza, ivanishi, kunye nelinoleum; kwaye njengemathiriyeli ekrwada ukuvelisa inani leekhompawundi eziphilayo.

INDLELA YOKUTHENGA KUTHI

I-Chemwin inokubonelela ngoluhlu olubanzi lwee-hydrocarbons ezininzi kunye nezinyibilikisi zeekhemikhali kubathengi bamashishini.Ngaphambi koko, nceda ufunde olu lwazi lulandelayo olusisiseko malunga nokwenza ishishini nathi:

1. Ukhuseleko

Ukhuseleko yeyona nto iphambili kuthi.Ukongeza ekunikeni abathengi ngolwazi malunga nokusetyenziswa ngokukhuselekileyo nokuhambelana nokusingqongileyo kweemveliso zethu, sikwazimisele ekuqinisekiseni ukuba imingcipheko yokhuseleko lwabasebenzi kunye neekontraka ziyathotywa ukuya kutsho kubuncinane obufanelekileyo nobunokwenzeka.Ngoko ke, sifuna ukuba umthengi aqinisekise ukuba imigangatho efanelekileyo yokukhutshwa kunye nokugcinwa kwemigangatho yokhuseleko idibene ngaphambi kokunikezelwa kwethu (nceda ubhekisele kwisihlomelo se-HSSE kwimimiselo jikelele kunye neemeko zokuthengisa ngezantsi).Iingcali zethu zeHSSE zinokubonelela ngesikhokelo kule migangatho.

2. Indlela yokuhambisa

Abathengi banokuodola kwaye bahambise iimveliso kwi-chemwin, okanye banokufumana iimveliso kwisityalo sethu sokuvelisa.Iindlela ezikhoyo zothutho ziquka iilori, uloliwe okanye uthutho lweendlela ezininzi (kuyasebenza iimeko ezahlukileyo).

Kwimeko yeemfuno zabathengi, sinokucacisa iimfuno zeenqanawa okanye iitanki kwaye sisebenzise imigangatho ekhethekileyo yokhuseleko / ukuhlaziya kunye neemfuno.

3. Ubuncinci bobungakanani bomyalelo

Ukuba uthenga iimveliso kwiwebhusayithi yethu, ubungakanani obuncinci bomyalelo ziitoni ezingama-30.

4.Intlawulo

Indlela yokuhlawula eqhelekileyo itsalwa ngokuthe ngqo kwiintsuku ezingama-30 kwi-invoyisi.

5. Amaxwebhu okuhanjiswa

La maxwebhu alandelayo anikwe ngokuziswa ngakunye:

· Ibhili yokuLading, i-CMR Waybill okanye olunye uxwebhu olufanelekileyo lwezothutho

· Isatifikethi sokuHlalutya okanye ukuThobela (ukuba siyafuneka)

· Amaxwebhu anxulumene neHSSE ngokuhambelana nemigaqo

· Amaxwebhu ezinto eziqhelekileyo ngokuhambelana nemigaqo (ukuba kuyafuneka)
